UNITED STATES PATENT OF ICE.

LOUIS C. H. MENSING, OF CHELMSFORD, COUNTY OF ESSEX, ENGLAND.

BUTTON.

SPECIFICATION forming part of Letters Patent No. 413,198, dated October22, 1889.

Application filed February 9, 1888- Serial No. 263,467. (No model.)

To all whom it may concern:

Be it known that I, LOUIS CARL HENRY MENSING, a subject of Her Majestythe Queen of Great Britain, residing at Chelmsford, in the county ofEssex, England, have invented new and useful Improvements in Studs,Cuff- Solitaires, and Similar Articles, of which the following is aspecification.

My invention relates to studs, cuff and collar buttons, and likearticles; and it consists of pivoted retaining-wings, to which isattached a slide or frame engaging with a screw secured to the cap orface of the article, the turning of which causes the slide to be movedand the wings either closed together or expanded.

In the drawings,Figure 1 is an elevation of a sleeve button embodying myinvention. Figs. 2 and 3 are central vertical sections thereof, thesections being taken at right angles to each other; and Fig. 4 is aninverted plan view of the button, the wings being extended.

The back or frame of the button or stud, (represented by the letter (Z)is provided with supports or connecting-pieces 0, upon which are pivotedor hung the wings a.

The cap or face 6 of the button or stud is provided with ascrew-threaded stud or stem 6, and with this screw engages a nut in theform of a slide or block f, which is connected with the wings a by meansof the arms I), which at their ends are pivoted or hinged to the wings.

The cap or face of the button has preferably its edges turned or spunover the edge of the back of the button, and is arranged to turn freelythereon in order to rotate the screwand operate the wings, but not tomove away or separate therefrom. The shank of the button-formed by theparts I) and cis considerably longer in the direction of the pivot ofthe wings than it is transverse thereto, as will be seen by a comparisonof Figs. 1 and 3, so t-hatwhen the button is inserted in a buttonholethe back, shank, and wing will be held against rotation, while the capor face may be turned in either direction.

In Figs. 1 and 3 the parts of the button are shown in the positionoccupied by them when the button is to be inserted into abutton-hole. Arotation of the cap or face will now cause the slide or block f to beraised or moved toward the cap or face 6, and by reason of this blockbeing connected, by thearms b, to the wings such wings will be turned ontheir pivots and caused to assume the expanded position indicated inFigs. 2 and 4, when it will be seen the button will be held in thebuttonholc'un til, by a rotation of the cap ,or face e, the wings areagain closed together, after which it may be removed.

It will be evident that the parts may be locked when in theiropen andclosed positions by means of slight indentations or recesses on theinner part of the cap or face 6, with which a projection on the back dwill engage. The slight spring obtained when the parts are properlyadjusted is found, however, to be sufficientfor this purpose.

What I claim is 1. In a stud or button, the combination of the back, thesupports carried thereby, the re taining-wings pivoted to such supports,a cap or face having a rotary movement only on the back and carrying ascrew, a longitudinally movable nut, and arms connected to the nut andto the wings, substantially as set forth.

2. The combination of the back, the supports 0 carried thereby, theretaining-wings pivoted in the supports, a cap or face connected withthe said back so as to have a rotary movement only thereon, a screwcarried by the cap or face, a block f, engaging with the said screw, andthe arms 1), connecting the block and the wings, substantially asdescribed.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

L. o. 1r. MENSING.
